Bill Gates, co-founder of Microsoft and now co-chair of the Bill and Melinda Gates Foundation, has held his very first AMA on Reddit. He’s surprisingly good at it, answering over 30 questions and verifying his identity in a number of cute ways (photo at left, video below). For the record, Gates’ preferred computer is the Microsoft Surface Pro, which he just got a week ago. He also believes that Windows 8 is better than Windows 7: “higher is better.” “I am using a Perceptive Pixel display right now — huge Windows 8 touch whiteboard,” he wrote. “These will come down in price over time and be pervasive.” Shockingly, the Microsoft founder also believes that Bing is “the better product at this point, seriously.” Concerning the future, Gates believes that “robots, pervasive screens, speech interaction will all change the way we look at ‘computers’.”
